VHF Radio Preamplifier Circuit
An antenna amplifier for the entire VHF broadcast band (100-175 MHz) which can be successfully built without any special test equipment. The grounded-gate configuration is inherently stable without any neutralization if appropriate PCB layout techniques are employed. The performance of the amplifier is excellent.

The noise figure is below 2 dB and the gain is over 13 dB. The MAX2633 is a low-voltage, low-noise amplifier for use from VHF to SHF frequencies. Operating from a single +2.7 V to +5.5V supply, it has a virtually flat gain response to 900 MHz.
